IMPROVEMENTW MACHINES FoRfuPsETTING T|REs;j

I To all'wtom it '77mg' concern: l

Beit known that I, GUSTAVE DANIELSON, of Boston', in the county of Suffolk and' State of Massachusetts, have invented a. new and Improved Machine for Shrinking' or Upsetting Tires for XVheels; and Ido hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a vertical section of my inven tion, taken in the ine x az, Fig. 2. Fig. 2l is a plan or top view of the same.

- Similar letters of reference indicate correspending parts in the two figures.

flhe object of this invention is to obtain a simple machine and one which may be very readily manipulated or operated for shrink` ing or upsetting tires for the wheels of vehicles, whereby the tires may, without being cut and rewelded, be adapted to suit the ydiameters of the wheels to which they are to be applied;

To :this e'nd the invention consists in a novel manner of clamping the tire, whereby the latter may be adjusted in or to the niachine with the greatest facility and in such a manner as to preclude the possibility of slipping while being compressed, while at the same-time one of the clamps is so arranged as to be capable of being moved under the action of a lever in order u.' contract the tire.

'To enable 'thoseseillcd iu the art to fully understand and construct my invention I willproceed to describe it.

A represents a framing on which a platform, B, is placed and permanently secured, and C is a segment ledge or projection which is attached to the platform B, and -is formed of a horizontal portion, a, and a vertical portion,

b, the upper surface of the former at one end being provided with a corrugated plate, c.' (Shown in Fig. 2.-) The ledge or projection Q .is stationary, and at one end of it there is a jaw, D, vwhich projects over the corrugated plate c of the part a of the, ledge C, and is attached to or formed on the upper end of a vertical bar, E, which passes through the platform B and is connected at its lower end by a linker joint, d, to alever, F, the fulcrum e 'of which lis secured to the under side ofthe platform 13.*, The lever F is notched-at its upper side, as shown at c', to receive the end .of a pawl, G, which is connected to the edge Specification forming part of Letters Patent N0. 36,5095 dated September ZS, 1862. I

of thel platform B by a joint orhinge, e, ,and

the -lever Frests ou a bar, H, which is attachedA to an `elliptic spring, I, in the framing Ar J is a jaw, which i's formed at the upperend of avertical bar, K,the latter passing through 1 a slidingplate, L, on'the platform B, and also through a pendent neck-piece, f, attached thereto, the neck-piecef being fitted in a slot, g, in the platform adjoining the 'end of the ledge C,l 'as shown clearly in Fig.2. To the bottom of the neck-piecef there is attached a,

plate, h,'which fits against the under side of 'the platformB, as'shown in Figi-1. Theneckpiece f is allowed to -slide freely in the slot g, and the lower end of the bar K is connected by a link-joint, h,fwith a lever, M, the ful-- crum lofwhich is attached to the plate h. l The lever M isalso notched at its upper side, n

as shown at a" to receive the end of a pawl, N, which is connected tothe edge of the platform B by a hinge or jointj.

In the upper' surface of-the plate L there is 4ledge C and the' other end against the plate v L, said spring having a tendency to keep the plate L outvfrom the ledge, as will be understood by referring to Fig.2.-

To the uppersurface of the platform B there is also attached by a fulcruni-pin, l, a lever, Q, the inner part, m, of which is of' cam form, as shown clearly in Fig. ,2.

The operation is as follows: The tire to be operatedupon is heated-at the desired part and the heated portion laid on the horizontal part a of the ledge C and against the upright or vertical part b, thetire being in a horizontal position, and the plate L being atthe extent of its movement from the ledge C, and the jaws D J being elevated in consequence of `the action of the spring I on the levers F M.

Vhen the tire is adjustedas described, the

loperator presses down` the levers F Myandl thejaws DJ are ,forced downupon 'the tire at each sidevof the heated portion, the levers be- .ing held as they are forced down by lthe pawls G N catching into the lnotched surfaces of the levers. When the tire is properly clamped, the plate L is forced toward the ledge C by actuating the lever Q., and the heated portion of the former between the two jaws is upset or contracted, so as todiminish the diameter of the tire, as required.

The advantage of this invention consists in the facility with which the machine may he manipulated. The tire may be very expeditiously and firmly clamped inthe machine, as the levers F M admit of the jaws D J being forced down with considerable power. The arrangement also admitsof the tire being adjusted on or to the machinewith the greatest facility, and the labor of but one man is required to perform thenecessary work.

I do not claim separately any of the parts herein described; but

I do claim as new and desire to -secure by Letters Pat-ent- 1. The attaching of the jaws D .I tovertical bars E K,-one of which. passes 4through the platform B and the other through the neckpiece fof the plates L h.. g

2; The arrangement of the jaws D J, bars E K, levers F M, spring I, and pawls G N, in combination with the-stationary ledge C on the platform B, the spring P, lever Q, and the sliding neclrpiecef, provided with the plates L h,through which the bar- K ,passes and to which the lever M is connected, substantially as and for rthe purpose herein set forth.

G. DANIELSON.
